What You'll Learn
Roasted soybeans can be stored in a mason jar in a cabinet
Roasted soybeans are a nutritious snack with a crunchy texture similar to nuts. They are made by roasting soybeans in an oven after soaking and drying them.
To store roasted soybeans, you can place them in a mason jar and keep them in a cabinet, as suggested in the query. This storage method will help keep the soybeans fresh for quite a long time. However, it is important to note that the soybeans should be cooled to room temperature before placing them in the jar and ensure that the jar is airtight.
The ideal storage conditions for roasted soybeans are in a cool, dry, and dark place, away from heat sources and direct sunlight. The temperature should be maintained between 40-70°F (4-21°C), and it is recommended to keep the humidity levels below 60% to prevent moisture absorption.
Additionally, it is a good practice to inspect the stored soybeans regularly for any signs of spoilage, such as mold growth, discoloration, or unusual odours. If any of these issues are detected, the affected soybeans should be discarded.
For longer-term storage, you can consider transferring the roasted soybeans to an airtight container or freezer bag and placing them in the freezer. This will extend the shelf life of the soybeans beyond what is possible with cabinet storage.

They are a good source of protein
Roasted soybeans are a good source of protein and can be used to feed chickens and dairy cattle. Soybeans are a versatile and nutritious legume with a range of applications in food production and industry. They are packed with protein, fibre, and essential vitamins and minerals, and contain all nine essential amino acids, making them a complete protein source.
Soybeans are typically roasted at temperatures between 290 to 315°Fahrenheit (143 to 157°Celsius). The roasting process can increase the amount of rumen undegradable protein (RUP), which can boost milk and/or milk protein yields. However, overheating soybean feed can reduce protein digestibility and render amino acids unavailable for metabolism. Therefore, it is important to find the optimal roasting temperature and duration to ensure the final product maintains its nutritional value.
Roasted soybeans have a crunchy texture and can be consumed as a healthy snack. They are an excellent source of protein, making them a popular choice for vegetarians and vegans seeking to increase their protein intake. Soy nuts, or roasted soybeans, are also rich in fatty acids, particularly unsaturated fats, which are known to support heart health.
When stored correctly, roasted soybeans can last for several months. To maximise their shelf life, it is recommended to store them in airtight containers in a cool, dry, and dark place.

They are a healthy snack
Roasted soybeans are a healthy snack option for several reasons. Firstly, they are a good source of protein, which is essential for muscle repair and growth. They also contain fibre, which aids digestive health and contributes to a feeling of fullness, making them a helpful snack for those looking to manage their weight.
In addition, roasted soybeans are rich in antioxidants and unsaturated fats, which are beneficial for heart health. They are low in saturated fat, helping to maintain lower cholesterol levels. Roasted soybeans also contain isoflavones, which have been linked to improved cardiovascular health.
When it comes to preparation, roasted soybeans are easy to make. The process involves soaking the soybeans, then roasting them in an oven with salt or other seasonings. They can be enjoyed as a standalone snack, or added to dishes like trail mix, salads, or blended into tea for added flavour and nutrients.
However, it's important to note that soy is a common allergen, and roasted soybeans should be consumed in moderation as part of a balanced diet. Proper storage is also crucial to maintain freshness and prevent spoilage. Roasted soybeans can be stored in airtight containers in a cool, dry place, and they will typically last for several months.

Roasted soybeans are best for older pigs
Soybeans are a versatile and nutritious legume with diverse applications in food production and animal feed. Roasted soybeans, in particular, are a popular choice for farmers due to their high protein content and the fact that they can be produced and processed on the farm itself.
When it comes to using roasted soybeans as animal feed, it is important to consider the age of the animals and the roasting temperature. While raw soybeans are generally safe for human consumption, they contain trypsin, which is toxic to birds and can cause intestinal scarring. For farm animals, some level of heating or roasting is necessary to destroy protease inhibitors that reduce protein digestibility and other anti-nutritional factors.
According to research, dry-roasted soybeans are best suited for older pigs. This is because younger pigs are more susceptible to anti-nutritional factors, and the high temperatures required to fully deactivate these factors can lead to protein deterioration. The optimal roasting temperature for soybeans intended for pig feed is between 290 and 315 degrees Fahrenheit. It is important to cool the soybeans after roasting and before feeding them to pigs.
Additionally, the storage method for roasted soybeans plays a crucial role in maintaining their quality and nutritional value. They should be stored in airtight containers, kept in a cool, dry, and dark place, and inspected regularly for any signs of spoilage. Proper storage conditions can extend the shelf life of roasted soybeans, making them a cost-effective and nutritious option for animal feed, especially for older pigs.

They can be fed to chickens to restore cold-weather laying
Roasted soybeans can be fed to chickens to restore their laying capacity during cold weather. This is because, as the weather cools, insects—a source of protein for hens—disappear. Soybeans are a good substitute for this protein. They also complement the large amount of grains that hens consume, making a complete protein in their diet.
To prepare soybeans for chickens, start by soaking dried soybeans overnight in several times their depth of water. The next day, bring them to a full boil (in the soaking water, to save vitamins), then slow boil for 15 minutes with the cover on loosely. After boiling, dump the beans into a strainer to cool. When cool, put them into the refrigerator. This process makes enough soybeans to feed around 10 hens for a few days.
It is important to note that the trypsin in all beans is toxic to the lining of birds' intestines and can scar their intestines, making them less able to absorb their food. Therefore, any beans fed to chickens need to be heated to at least 180 degrees Fahrenheit for a minimum of 15 minutes to destroy the trypsin. The best way to do this is by boiling. Soybeans can also be dry-roasted (without soaking) at around 250 degrees Fahrenheit, but this method is more cumbersome and less certain to destroy the trypsin. To ensure all beans reach the necessary temperature, they must be continually turned.
